Her sword clashed with his baton, unleashing all the energy meant for her arm into the blade instead, and he instantly used his grip on her foot to jerk her toward him while simultaneously extending the blade in his left gauntlet. From where it was positioned, her raised hand would be pulled straight through the blade and the arm would be split in two for a fair length before the blade finally cut through the bone of the elbow and out of her flesh. Her own defense, unless supplemented by some unknown strength, would prove too weak to prevent this series of events from happening, and it would all be over before any normal human could even blink, such was the speed at which he moved. 

If, however, she managed to fire the shot before he took the hand out of commission, he'd abandon the slice at her hand and duck down and to his own right as soon as the energy visibly coalesced, sliding his staff down the blade of her sword until it struck the crossguard and from there driving it down and back farther still, using his superior strength and leverage to push her own blade directly toward her face as he pulled her closer.
